GRATE-OPERATING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 631,746, dated August 22, 1899.

Application filed June 23, 1899.

To all whom it may concern..-

Be it known that 1, JOHN A. KLINE, a citizen of the United States of America, and a resident of Reading, in the county of Berks and State of Pennsylvania, have in vented certain new and useful Improvements in Grate- Operating Mechanism, of which the following is a specification.

My invention relates to an improved oper- Io ating mechanism for rocking grates, the main object of which is to insure the return of the grate-bars to their normal position after operating the same, and thereby avoid the danger of burning them and the unsatisfactory support provided for the fuel when the bars are partially tilted.

The invention is fully described in connection with the accompanying drawings and the novel features are specifically pointed out in the claims.

Figure 1 is a sectional side elevation of my improved mechanism, showing the same applied to the ash-pit front of a heater and indicating the connection to a rocking grate, the parts being in normal position. Fig. 2 is a sectional front elevation of the same. Fig. 3 is a similar view to Fig. 1, but showing the lever moved outward to tilt the grate-bars.

A represents the front plate of an ash-pit, and G one of a series of pivotally-mounted grate-bars having drop-ears g, connected by a bar G, to which horizontal movement is imparted,as usu al,through the lever connectingrod E to effect the rocking of the grate-bars either for cleaning or dropping the fire. The

lever C, to which the connecting-rod E is piv-' oted at c, is fulcrumed at its lower end 0 to a lug a on the ash-pit front and is provided, as usual, with a detachable handle extension D,the socketed lower enddbf which is dropped into engagement with the shank portion 0 of the main lever 0 when the latter is to be moved to operate the grate. The connectingrod E passes through an opening a in the ash-pit front and is provided with shoulders e e, which ordinarily serve 'to limit the toand-fro movement by coming in contact with a swinging stop 13 on the ash-pit front,said stop being raised to permit of the grate movement semi No. 721,537. (No model.)

required to tilt the grate-bars sufficiently to drop the fire.

The construction above described is well known and its operation is satisfactory except for the liability of the operator failing to return. the parts to their normal position before leaving the same, which failure, as already stated, is apt not only to affect the condition of the fire, but also to damage the grate by subjecting the raised portions thereof to undue heat. I To overcome this danger and insure the return of the bars to their proper positions Without requiring the operator to use the care ordinarily demanded, I provide one branch of the connecting-rod jaw c with a quadrant-shaped extension F, having an inwardly-projecting concentric flange f, and

' near the bottom of the socketed end of the detachable handle D, I provide an exterior side projection 01, which in placing the partD upon the shank c readily passes below the overhanging flange f when the lever is in its normal position, said flange being notched at f to permit this. As soon as the lever is moved, however, from this normal position the projection d fails to register with the notch f and the lever-handle D is looked upon the shank c and cannot be removed therefrom, as

is customary after each operation of the grate, until the parts are returned to their original and proper position. In Fig. 3 the lever is shown moved outward sufficiently to turn the grate-bars for dropping the fire, the stop B being raised to permit the passage of the shoulder e, and the handle D is locked to the other parts, while in Fig. 1 it is ready to be removed, leaving the grate-bars in proper position.

What I claim is- 1. The combination with a rocking grate of a two-part lever for operating the same com- 0 prising a main part and a detachable part,

and a grate-connecting bar pivoted to said main part and provided withlocking means adapted to engage said detachable part except when the grate is moved to its normal 5 position.

2. The combination with a rocking grate of a two-part lever for operating the same com- Signed by me at Reading, Pennsylvania, this 12th day of J nne, 1899.
